CAR SEAT.

Application filed March 18, 1921. Serial No. 453,459.

To all whom it may concern:

Be it known that I, ALBERT L. Listener, a cltlzen of the United States,reslding at Narbeth, in the county of Montgomery and State ofPennsylvania, have invented certain new and useful Improvements in CarSeats, of which thefollowing is a specifica-, j the line 3.3 of F 1g. 2,and Fig. 4: 1s a hor My invention relates to reversible carseats 1 tion.

for railway carriages and the like and one of the objects of thisinvention is to provide for this typeof seat an improved seat end whichposseses great strength, which can be manufactured at small cost, whichis arranged to facilitate the application thereto of the seat-reversingmechanism, and one which permits of the concealment or covering of theparts of the seat which are attached thereto so as not to be in the wayof a passenger moving down the aisle.

A further object of my invention applies particularly to thewell knownreversible car seat construction wherein the back standards carryrollers mounted to travel back and forth in channel tracks carried onthe seat'ends. Due to the vibration of the mov: ing train these rollersare aptto be joggled about between the upper and lower members of thechannel track, particularly when the seat is unoccupied,-and suchjoggling occasions considerable noise and rattle. The particular objectinvolved is to provide means to prevent the rollers from joggling orrattling about in the channel track and thus to eliminate theobjectionable noise and rattle above referred to.

Other objects of this invention will be in.

part obvious andin part pointed out hereinafter. i r

I will now describe a reversible car seat of a well known type,confining my descrip- 7 a side elevation of a reversible car seat,em-

bodying my invention, the back being shown in one of its extremepositions; Fig. 2 is a plan view of the end plate of the car seat builtaccording to my invention" and. inriudes, diagrammatically, the rollerscarried by the back standard and my invention applied thereto; Fig. 3 isa. vertical section of my improved end plate taken on Similar referencecharacters designate similar parts throughout the several views of thedrawings.

Referring to the drawings,the reference,

character 1 represents theusual aisle pedestal, 2 and 2 the crossmembers, supported on the aisle pedestal and the wall support for theseat, 3 the seat cushion (shown in dotted lines) supported on crossmembers 2 and 2, 4 the usual back provided on its edges with metallicstandards, one of which is shown at o, carrying at its lower end rollers6. and 7, which are mounted to be moved back and forth in curved channeltracks'carried on the seat ends, one of which is shown at 8, of the carseat, inthe well known manner.

Since my invention relates to the novel and improved end plate for theseat, sometimes called seat end, the seat end will now be described indetail. In accordance with my invention the seat end 8 is formed from. asingle pieceof sheet metal of a weight and strength sufficient ,to givethe required. strength. The channel track for the rollers 6 and '7 isformed on the inside surfaceof the seat end by pressingor otherwiseshaping the piece of sheet metal in such away that it will present twoparallel, spaced folds or flanges 9 and 10, extending inwardly andlongitudinally acrossthe seatend and forming a channel track, comprisingrespectively lower track member 9 and upper track member 10, as shown.At each extremity of these track members a portion of the piece of sheetmetal. is pressed inwardly to provide a flange 11 forming a stop for therollers 6 and 7 when they reach the extremities of the track. Heretoforeithasbeen customary to form the channel track separately from the seatend and'to secure it to the inner tace of the seat end with rivets or byweld- 7 integraletherewith, considerable saving ot'expense and time-iseffected in the manufacture of the seat end and considerable saving innaterial isefiiected, and at the same time space-fat the ends ofthe seatisconserved.

' As a further improvement. in seat end construction, the end plate maybe formed to present integral portions suitable for the attachmentthereto of parts of the seat mechanism. One of these portions, asillustrated, co'mprises'a boss12 below the channel'track formedintegrally on the seat end,

at its centre, and has a perfoi ation 13 adapted to receive the "usualbushing 13. for

one end of a rocker rod. Boss 12 provides on the exterior of the scatend a-pocket of such depth that the end of the bushing 13' or the rockerrod, or aretainin'g nut thereon will not extend beyond the outer surfacebolted thereto, as at 1 8, and to the cross member 2, as at 20, in theusual manner,

with the bolt head or nut on the bolt 18 toward the outside of the seatend seated in the pocket with no part extending beyond the outer surfacethereof.

7 Thus it is apparent that a seat end of the above configlllltttlOll andconstruction maintains all the arts of the seat mechanism which areconnectedthereto, out of the way of'a passenger traveling down the aisleand so masks these parts that they are not likely to catch desired.

against a grip carried by a. passenger nor to catch into and tear apassengers clothing. An nwardly extending peripheral flange 21 maybe'formed about the seat end, and

a cover plate 22 provided with a correspondinglnwardly extending flange23, may be applied to the outside of the seat endwith flange 23'overlapping flange 21, to further mask the parts of the seatmechanisniwhich are attached to the seat end for'the'pu'rpose The cover plate maybe joined to the seat end by welding or the like and in this manner asmoothflat surface may be any "suitable design supplied thereto.

provided for the outside of the seat end, or The welding operation maybe dispensed with by bending or pressing the flange 23 of cover plate 22about the inner edge of flange 21 as shown at 24. vAt the extremities ofthe channel track the end plate and the flange 28 of the cover plate 22may be brought together by continuing flange 11 of the end plate atright angles and until it abuts flange 23 as at 2 1. The surface of theseat end, even without the cover plate, is sufficiently flat for directattachment to the car wall at the wall side of the seat.

drop into depression 26.

the full distance between the rollers when they are in normal positionon the track, as is shown by dott-edllines in Fig. 2. Each end of thisblock 25 presents a sloping surface receding upwardly from the, adjacentroller. At each end of the lower channel track member? is'tormed adepression 26 and 26, respectively, into which the outside roller isadapted to fall as the roller approaches the end of the channel trackand the seat reaches either extreme position. [is the outside rollerdrops into a depression the inner roller will ride upwards on theadjacent surface of member 25 so as to be firmly held against the upperchannel track member 10, and while the seat is in an extreme positionthe inner roller will be so firmly held again t the'upper channel trackthat it will be prevented from vibrating or rattling, and 11121 notoccasion objectionable noise by so doing.

In operation it has been found that the provision of member 25 in no wayretards or hinders the easy reciprocation oi theback in the usualmanner. As the back appreaches one extreme position, for instance,

the position illustrated in Figs. 1 and 2,

roller 7 will roll into depression 26 and member 25 will thereby be heldagainst further horizontal movement, and as roller 7 drops further intothe depression, roller 6 will ride up on the surface 27 of member 25until it is firmly pressed against the upper channel track member 10, asat 28 by the weight of the back which causes roller 7 to Similarly whenthe back is reversed, roller 6 will drop into depression 26 and roller 7will be held against vibratory movement in the channel track on accountof its having ridden upward on surglace 29 of member 25 and is beingfirmly pressed against the upper; channel track member 10 by the weightof the back which causes roller 6 to sink into depression 26.

It is believed that applicants invention relating to means for avoidingthe objectionable noise as above described is broadly new, and sincemany changes'c'ould be made inthe above construction and many apparentlywidely different embodiments o f'this invention may be madewitho'ut'departing from the scope thereof, it is intended that allmatter contained iir'the aboved escription or shown in the accompanyingdrawings shall be interpreted as illustrative and notin a limitingsense. i
